6 months since last period
I am a 23 yo female and it will be six months since my last period on the 28th of this month. I have been having pain in my lower abdomen, left side, for quite a while now. I am not on birth control and a normal period for me is every 2-3 months and I do have pain during intercourse. My husband has already taken me to the ER due to crippling abdominal pain and because I am uninsured there was not much they could do for me as far as ultrasounds go. I have taken urine pregnancy tests and they have come out negative, but my concern now is that I have been getting light headed and the other day I almost passed out while I was driving. Reading over this for a normal person it seems pretty serious but having no insurance and getting hit with the bill after anything that has to do with the doctors does not settle well. Are there any signs I should look out for as far as I could possibly die if I do not seek treatment or ideas on what this might be?
